Filed: 1999-07-30
Abstract: PROBLEM TO BE SOLVED: To provide a compact zoom lens realizing rapid focusing and constituted of the comparatively small number of lenses by specifying constitution of the lens. SOLUTION: This zoom lens is provided with four lens groups, that is, a 1st lens group L1 having positive refractive power, a 2nd lens group L2 having the negative refractive power, a 3rd lens group L3 having the positive refractive power and a 4th lens group L4 having the positive refractive power in order from an object side. Variable power from a wide-angle end to a telephoto end is performed by widening a distance between the 1st group L1 and the 2nd group L2 and narrowing the distance between the 2nd group L2 and the 3rd group L3, and fluctuation of an image surface associated with the variable power is compensated by moving the 4th lens group L4. Simultaneously, focusing is performed by moving the 4th group L4.  The 3rd group L3 is provided with a diaphragm on the side nearest to the object, and is composed of a combined lens consisting of a positive lens and the negative lens both of which are convex on the image surface side and the meniscus negative lens whose concave surface faces to the image surface side. The 4th group L4 is composed of the positive single lens whose convex surface faces to the object side or the combined lens of the positive lens and the negative lens.

IPC: G05B19/05
Filed: 1994-09-13
Abstract: PURPOSE: To simultaneously satisfy real-time throughput at a level required for the control of an FA system and the flexibility of FA system constitution by limiting the communication method of executing states among plural programmable controllers just to message exchanges to be independently performed by respective controllers. CONSTITUTION: In order to reduce the required time of a processing request, a star connecting state is adopted for directly connecting a programmable controller 14 and a low-order message exchanging device 16 and directly connecting the device 16 and a high-order message exchanging device 17 by one-to-one and waiting time with line control is excluded. Besides, in order to reduce delay time up to the reception of the processing request, the connecting capacity of the devices 16 and 17 is limited, the data structure of the processing request is made routine and further, the time required for preprocessing is shortened by facilitating the decision of processing request contents. Thus, the communicating method of the executing states among the controllers 14 is limited just to the message exchanges to be independently performed by the respective controllers 14.

Title: Gusset bag and packaging machine
Inventor: YAMANO MASARU
IPC: B65B43/54
Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To bind a gusset bag with a cord or the like easily and neatly as when the bag is squeezed, by extending out the inside-folded parts of the opening of the gusset bag and by heat-sealing its right-bag sheet and left-bag sheet facing each other. SOLUTION: In a gusset bag 1, ridges (e) and (f) are formed by folding inside both ends ab and cd of a right-bag sheet 2a and left-bag sheet 2b both of which have the same size and are made of a synthetic fiber. In the case of packaging by the use of such a gusset bag 1, two sheets 2a and 2b extended out are bitten at both ends of the gusset bag 1 by means of a pair of biting pawls. Then, while the condition is maintained, the gusset bag is opened in an opening process, stuff is filled into it, and subsequently the opening 4 is heat-sealed to heat- seal the two sheets 2a and 2b together. At the time, the ridges (e) and (f) are in the form of outer ends [in which (a) and (b) coincide with each other and (c) and (d) coincide with each other]. This makes it possible to bind the opening 4 with a cord or the like neatly with the opening squeezed.

Title: Reset circuit
Inventor: KASHIMA TETSUSHIGE
IPC: G06F1/24
Filed: 1988-08-31
Abstract: PURPOSE:To inhibit the output of reset signals to other devices despite the coincidence obtained an address signal with the value of a decoder and to give no influence to the actions of other devices by keeping a write signal under a valid state for a fixed time only when the write signal is received from a microprocessor. CONSTITUTION:An IO WRITE signal 10 received from a microprocessor is inputted to a flip-flop 1, and a logically high level signal is outputted from a Q terminal of the flip-flop 1. At the same time, a logically high level signal is also outputted from a Q terminal of a flip-flop 2 and inputted to a clock CLK terminal of the flip-flop 2 with a delay equal to a fixed time T. Thus a signal of a fixed time width T is generated regardless of the pulse width of the signal 10. The data 71 - 7N received from the microprocessor are latched by a flip-flop 3 and outputted to other devices as the reset signals 11 - 1M. Then a new reset signal is never outputted since the data 71 - 7M are not latched even though the coincidence is secured between the address signals 81 - 8N and the set value of a decoder 6.

SOLUTION: A line sensor 1 converts an optical signal into an image signal which is an electrical signal and a sample-and-hold circuit 2 which follows the signal sample-and-holds the image signal by each pixel. The output of the circuit 2 is sent to a VCA circuit 3 to be amplified so as to be a signal of a prescribed amplitude. The circuit 3 is given a VCA setting signal sent from a CPU 10 via a D/A converter 6 and amplifies it to make the prescribed amplitude. The output of the circuit 3 enters a clamp circuit 4, and the output of the circuit 4 enters the A/D converter 5 to be converted into digital image data. UPU 10 monitors the output of the converter 5 at all times and changes a VCA set value, when the output is small.
